BRIEF DESCRIPTION
In the following description, numerous specific details are set forth, such as examples of specific shapes, components etc., in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well known components or methods have not been described in detail, but rather in general terms in order to avoid unnecessarily obscuring the present invention. Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present invention.
Reference to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment. It will also be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present.
It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the following discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices. It is further contemplated within the scope of this invention that calculations can also be done mentally, manually or using processes other than electronic.
FIG. 1 illustrates a charge coupled device (CCD) light sensor board 10, in accordance with the teachings of the present invention. One such light sensor board 10 is associated with each player position around a gaming table, as shown and described below in greater detail. The CCD light sensor board 10 generally comprises a cadmium sulphide sensor 12 whose resistance changes in response to light, as powered from a cable 20 through a conductor 22. The light sensor 12 pulls against a resistance 24 to create a changing voltage point, in a manner known in the art. This changing voltage point is measured using an Analog to Digital (A/D) converter 26 through a conductor 25 and calibrated continuously to detect changes in light through fabrics and changing lighting conditions. The light sensor board 10 also contains a light-emitting diode 28 which serves as a location indicator and is optically isolated from the light sensor. The entire light sensor board assembly is preferably mounted to a gaming table beneath the table-covering felt with a set of mounting holes 30.
As shown in FIGS. 1 and 2, a tabletop 40 includes a light sensor 12 mounted in a hole 14 in the tabletop. The light sensor 12 is mounted in such a way that it is substantially flush with the top surface of the tabletop. A felt layer 16 is installed over the tabletop over the light sensor. The light sensor senses changes in light entering the light sensor through the felt. When a new felt is installed, a registration pattern 18 FIG. 1), which is printed on the felt, is installed over the light sensor. So, when a chip or a card is placed over the sensor, or even if it just passes over the sensor, the sensor detects the change in ambient light and informs the data collection system.
FIG. 3 illustrates one preferred embodiment of a reporting system using the card and chip detection system of FIGS. 1 and 2. The tabletop 40 is covered with a felt layer 16, as previously described. A dealer's position 42 is positioned along one location beside the gaming table, while a plurality of player positions 44 are arrayed in a semi-circle along the side of the table. A sensor 12 is positioned adjacent each player position.
Each of the sensors 12 is coupled electronically with a processing board 46 through a connection 48. The processing board 46 is electronically coupled to a central processing unit (CPU) 50, possibly wirelessly, through a connection 52. In various embodiments, the connection 52 includes a transceiver assigned to the table that receives data from the processing board 52 and transmits the data to the CPU 50. The transceiver may be, for example, a computing device that communicates via wired Ethernet or wirelessly. In a typical embodiment, the CPU 50 is representative of a management system such as, for example, a casino management system, and may be representative of one or more physical or virtual server computers. In a typical embodiment, the CPU 50 stores for and facilitates management of a plurality of gaming tables.
Preferably, each of the sensors 12 is monitored continuously, so that any alteration in the state of the A/D converter 26 (FIG. 1) associated with any sensor will be sensed by the processing board 46 and transmitted to the CPU and stored. This allows the proprietor to maintain an up to the minute determination of the gaming at each player position throughout the establishment, such as for example in a casino.
FIG. 4 illustrates another embodiment of a reporting system using the card and chip detection system of FIGS. 1 and 2. In particular, a gaming table 400 is illustrated. For purposes of simplicity, the sensors 12 illustrated with respect to FIG. 3 and described above are grouped together in FIG. 4 as a first group 60. A second group 58 of the sensors 12 is disposed above the first group 60 and adjacent to the player positions 44. A dealer keypad 102 and a card-reading apparatus 104 are positioned on the tabletop 40 in proximity to the dealer's position 42.
The dealer keypad 102 and the card-reading apparatus 104 are electronically coupled to the central processing unit (CPU) 50 through a connection 54 and a connection 56, respectively. In various embodiments, the connections 54 and 56 include a transceiver assigned to the table that receives and transmits data to the CPU 50. In the case of the connection 54, the transceiver may relay data intended for the dealer keypad 102 from the CPU 50 to the dealer keypad 102. The transceiver may be, for example, a computing device that communicates via wired Ethernet and/or wirelessly. In various embodiments, the connections 48, 54, and 56 may share a single transceiver.
The dealer keypad 102 and the card-reading apparatus 104 allow a dealer to practice more efficient management of players at the gaming table 400, for example, in a casino pit. Operation of the dealer keypad 102 and the card-reading apparatus 104 will be described in greater detail with respect to FIGS. 5-8.
In a typical embodiment, the sensors 12 in the second group 58 facilitate additional bets such as proposition bets (i.e. side bets). One of ordinary skill in the art will appreciate that a proposition bet refers to a bet made regarding the occurrence or non-occurrence during a game of an event not directly affecting the game's outcome. For example, during a game of blackjack, proposition bets could be established related to which cards will be dealt (e.g., a “Lucky Ladies” proposition bet that wins only if a player is dealt the queen of hearts and the dealer receives blackjack). Numerous types of proposition bets are possible and will be apparent to one of ordinary skill in the art.
In a typical embodiment, the sensors 12 in the second group 58 may be used to determine whether a proposition bet has been placed. If one or more gaming objects (e.g., chips) are placed over any of the sensors 12 in the second group 58, the alteration in the state of the A/D converter 26 (FIG. 1) associated therewith will be sensed by the processing board 46 and transmitted to the central CPU 50 and stored. In that way, the central CPU 50 stores each proposition bet and can track proposition bets and the frequency with which particular players make proposition bets. This allows the proprietor to maintain an up to the minute determination of proposition bets at each player position throughout the establishment such as, for example, in a casino.
FIG. 5 illustrates the dealer keypad 102 and the card-reading apparatus 104 of FIG. 4 in greater detail. The dealer keypad 102 includes a display 208 that may be, for example, a liquid crystal display (LCD). The dealer keypad 102 additionally includes a numbered section 516 and a command section 518. The numbered section 516 includes a plurality of numbered buttons 512a and a plurality of indicator lights 514a that are each associated with one of the numbered buttons 512a. The command section 518 includes a plurality of command buttons 512b and a plurality of indicator lights 514b that are each associated with one of the command buttons 512b. 
For simplicity of reference herein, individual buttons in the plurality of numbered buttons 512a or the plurality of command buttons 512b may be referred to by a label appearing thereon (e.g., “the numbered button 512a labeled ‘1’” or “the command button 512b labeled ‘#’”). Likewise, for simplicity of reference, individual indicator lights in the plurality of indicator lights 514a or the plurality of indicator lights 514b may be individually pointed out with reference to an associated button from the plurality of numbered buttons 512a or the plurality of command buttons 512b, respectively (e.g., “the indicator light 514a associated with the numbered button 512a labeled ‘1’” or “the indicator light 514b associated with the command button 512b labeled ‘#’”). Finally, for further simplicity, individual indicator lights from the plurality of indicator lights 514a or the plurality of indicator lights 514b may be individually pointed out solely with reference to a label appearing on a button with which it is associated (e.g., “the indicator light 514a associated with ‘1’” or “the indicator light 514b associated with ‘#’”).
In general, numbers that appear on the plurality of numbered buttons 512a correspond to a player position such as, for example, one of the plurality of player positions 44. For example, with reference to FIG. 4, each of the plurality of player positions 44 can be assigned a position number from one to six (e.g., from left to right from the dealer's perspective). With reference to FIG. 5, the display 208 indicates, by way of example, that position numbers one, two, three, and five are occupied while position numbers four and six are vacant. In a typical embodiment, the dealer keypad 102 additionally represents table occupancy by causing indicator lights 514a associated with occupied player positions to be lit. For purposes of the example depicted in FIG. 5, the dealer keypad 102 lights the indicator lights 514a associated with the numbered buttons 512a labeled ‘1’, ‘2’, ‘3’, and ‘5’.
Still referring to FIG. 5, the card-reading apparatus 104 is typically operable to accept, for example, a card having a magnetic stripe 206 disposed thereon. In a typical embodiment, the magnetic stripe 206 includes information that uniquely identifies, for example, a player. The information can be used to access biographical or historical data regarding the player. For example, in operation, the card may be oriented so that the magnetic stripe 206 faces left on the card-reading apparatus 104 and is swiped in a downward direction.
Exemplary functionality of the dealer keypad 102 will now be described. In various embodiments, the dealer keypad 102 facilitates dealer check-in functionality. Prior to a dealer being checked-in, operation of the dealer keypad 102 is typically locked. To check-in, the dealer swipes an employee card using the card-reading apparatus 104. With reference to FIG. 4, the card-reading apparatus 104 transmits identification information gleaned from the employee card to the CPU 50 via the connection 56. The central CPU 50 registers the dealer for the gaming table 400 and returns the registration to the dealer keypad 102 via the connection 54. At the dealer keypad 102, the indicator light 514b associated with the command button 512b labeled ‘✓’ becomes lit. After the dealer presses the command button 512b labeled ‘✓’, the associated indicator light 514b turns off and the dealer's name appears on the display 208. At that point, functionality is unlocked and the dealer is enabled to operate the dealer keypad and perform, for example, the functionality described below.
In various embodiments, the dealer keypad 102 facilitates player check-in functionality. In various embodiments, the dealer keypad 102 enables player check-in with or without a cash buy-in. Exemplary functionality for checking-in a player without a cash buy-in will be described first.
To check-in a player without a cash buy-in, the dealer swipes a player card using the card-reading apparatus 104. With reference to FIG. 4, the card-reading apparatus 104 transmits identification information gleaned from the player card to the CPU 50 via the connection 56. The CPU 50 subsequently indicates to the dealer keypad 102 that a player registration process is occurring and the dealer keypad 102 causes the indicator light 514b associated with the command button 512b labeled ‘✓’ to become lit. At this point, the dealer presses the command button 512b labeled ‘✓’ again and then presses the numbered button 512a labeled with a desired position number at the gaming table 400 (e.g., ‘1’, ‘2’, ‘3’, etc.).
In some embodiments, a buy-in interface may appear on the display 208. In these embodiments, the dealer presses the command button 512b labeled ‘✓’ again to exit the buy-in interface. The desired position number and the buy-in amount (i.e., zero) are transmitted to the CPU 50 via the connection 54. Then, the CPU 50 confirms the player registration and transmits a desired alias such as, for example, the player's first name, to the dealer keypad 102. At this point, the player's alias (received from the CPU 50) appears on the display 208 in connection with the desired position number at the gaming table 400. Also, the dealer keypad 102 causes the indicator light 514a associated with the desired position number to become lit.
Operation of the dealer keypad 102 to facilitate player check-in with a cash buy-in will now be described. Player check-in with a cash buy-in proceeds as described above with respect to player check-in without a cash buy-in except that the dealer does not immediately exit the buy-in interface. The buy-in interface on the display 208 allows the dealer to enter a buy-in amount as cash, chips, or marker. In a typical embodiment, the buy-in interface on the keypad 102 defaults to cash but can be toggled to chips or marker by pressing, for example, the command button 512b labeled ‘*’. In a typical embodiment, the dealer toggles between cash, chips, and marker as appropriate to select the appropriate type of buy-in.
To simplify buy-in entry, in some embodiments, the dealer keypad 102 may utilize a multiplier such as, for example, one-hundred, so that a $200 buy-in amount could be entered by pressing the numbered button 512a labeled ‘2’. In these embodiments, if the buy-in amount is not compatible the multiplier (e.g., the buy-in amount is not a multiple of one-hundred), the dealer can press, for example, the command button 512b labeled ‘#’ and enter the exact amount via the numbered buttons 512a. 
After the buy-in amount is entered, the dealer presses, for example, the command button 512b labeled ‘✓’, to indicate completion. The desired position number and the buy-in amount are transmitted to the CPU 50 via the connection 54. Then, the CPU 50 confirms the player registration and transmits a desired alias such as, for example, the player's first name (received from the CPU 50), to the dealer keypad 102. At this point, the player's alias appears on the display 208 in connection with the desired position number. Also, the dealer keypad 102 causes the indicator light 514a associated with the desired position number to become lit.
In various embodiments, the keypad 102 additionally enables the dealer to check-in a player who does not have a player card as a guest. To check-in a player who does not have a player card, the dealer presses, for example, the command button 512b labeled ‘✓’, which causes the associated indicator light 514b to become lit. The guest can be checked-in either with or without a buy-in as described above with respect to players with player cards. Subsequently, the keypad 102 notifies the CPU 50 of the guest's registration and transmits the guest's desired position number and any buy-in amount. Then, the CPU 50 confirms the guest registration and transmits an alias such as, for example, “guest,” to the dealer keypad 102. At this point, the alias appears on the display 208 in connection with the guest's desired position number. Also, the indicator light 514a associated with the guest's desired position number becomes lit.
In various embodiments, the keypad 102 additionally enables the dealer to enter an average bet for players at the gaming table 400. In a typical embodiment, the average bet is utilized, for example, to calculate player ratings for purposes of determining comps. To enter an average bet, the dealer presses, for example, the command button 512b labeled ‘*’ and presses the numbered button 512a that is labeled with the appropriate player position number. Subsequently, the dealer enters the average bet amount via the numbered buttons 512a and presses, for example, the command button 512b labeled ‘✓’ to indicate completion. The entered average bet amount is transmitted to the CPU 50 via the connection 54.
In various embodiments, the dealer keypad 102 enables the dealer to perform player check-out functionality. In a typical embodiment, players (and guests) can be checked-out from the gaming table with or without a walk-with amount. If a player is being checked-out without a walk-with amount, the dealer can press, for example, the command button 512b labeled ‘✓’ followed by the numbered button 512a labeled with the player's position number. Subsequently, the dealer keypad 102 notifies the CPU 50 and receives a confirmation from the CPU 50 that the player is checked-out. At that point, the indicator light 514a associated with the player's position number turns off and the player's name is removed from the display 208.
If the player is being checked-out with a walk-with amount, the dealer can press, for example, the command button 512b labeled ‘✓’ followed by the numbered button 512a labeled with the player's position number. Subsequently, the dealer enters an amount that the player is leaving the table with (i.e., a walk-with amount) using appropriate buttons from the numbered buttons 512a. Once the walk-with amount is entered, the dealer presses, for example, the command button 512b labeled ‘✓’, and the dealer keypad 102 notifies the CPU 50. Once the dealer keypad 102 receives confirmation from the CPU 50 that the player is checked-out, the indicator light 514a associated with the player's position number turns off and the player's name is removed from the display 208.
In various embodiments, the dealer keypad 102 enables the dealer to perform lobby functionality. For example, if a player gets up to take a break (i.e. lobbying), the dealer logs the player as temporarily away by pressing, for example, the numbered button 512a corresponding to the player's position number. In a typical embodiment, the indicator light 514a associated with the player's position number flashes to indicate that the player is lobbying. The player's status of lobbying is reported to the CPU 50. In this manner, the player's position at a gaming table is reserved but the player is not credited for time or hands when the player is not at the gaming table. In this manner, over-comping of players based on time not spent at the gaming table can be prevented. When the player returns, the dealer can again press the numbered button 512a corresponding to the player's position number and the indicator light 514a associated with the player's position number stops flashing.
In various embodiments, the dealer keypad 102 additionally enables the dealer to move players from one position number to another position number when, for example, a player desires to move to a different position at a gaming table. In various embodiments, the dealer can accomplish a move of the player via a three-button sequence. In particular, the dealer can press the command button 512b labeled ‘M’, the numbered button 512a corresponding to the player's current position number, and the numbered button 512a corresponding to the player's new position number. Then, the dealer keypad 102 notifies the CPU 50 of the move. Upon receipt of confirmation from the CPU 50, the dealer keypad 102 updates the display 208 to reflect the player's name at the new position number.
In various embodiments, the dealer keypad 102 also enables the dealer to more efficiently accommodate players that are playing at more than position number. Specifically, the dealer keypad 102 permits the dealer to copy a player's information from one position number to a second position number that will be occupied by the same player. In a typical embodiment, a copy can be accomplished via a three-button sequence. In particular, the dealer can press the command button 512b labeled ‘C’, the numbered button 512a corresponding to the player's current position number, and the numbered button 512a corresponding to the player's additional position number. At that point, the dealer keypad 102 notifies the CPU 50 of the copy. Upon receipt of confirmation from the CPU 50 that the copy has been accomplished, the dealer keypad 102 updates the display 208 to show the player's name at the additional position number.
In various embodiments, the dealer keypad 102 further enables the dealer to input additional cash buy-in for a player. To enter additional cash buy-in, the dealer can press, for example, the command button 512b labeled ‘#’ followed by the numbered button 512a corresponding to the player's position number. Then, the dealer keypad provides a buy-in interface to the dealer. After receiving the additional buy-in amount in a manner similar to that described above with respect to player check-in, the dealer can press, for example, the command button 512b labeled ‘✓’ to indicate completion. At that point, the dealer keypad 102 sends the additional buy-in amount to the CPU 50 via the connection 54.
FIG. 6 provides another view of the dealer keypad 102. For example, the display 208 illustrates a player checked-in as a guest.
FIG. 7 illustrates a process 700 for automatically checking-in a player as a guest. In contrast to the procedures described above with respect to FIGS. 5 and 6, the process 700 does not require data entry by a dealer. The process 700 begins at step 702. At step 702, a player approaches a player position such as, for example, one of the player positions 44 of FIG. 4. From step 702, the process 700 proceeds to step 704.
At step 704, a gaming object is placed at the player's player position. For example, the dealer may deal one or more cards to the player's position. From step 704, the process 700 proceeds to step 706. At step 706, with respect to FIG. 4, a sensor from the first group 60 that corresponds to the player's position detects a change in light intensity. From step 706, the process 700 proceeds to step 708. At step 708, the alteration in the state of the A/D converter 26 (FIG. 1) associated therewith is sensed by the processing board 46 and transmitted to the central CPU 50. From step 708, the process 700 proceeds to step 710.
At step 710, the CPU 50 determines whether the player's position is vacant. If not, the process 700 proceeds to step 716 and ends. Otherwise, the process 700 proceeds to step 712. At step 712, the CPU 50 registers a guest at the player's position at the gaming table 400. From step 712, the process 700 proceeds to step 714. At step 714, the CPU 50 transmits the guest registration to the dealer keypad 102 via the connection 54. The dealer keypad 102 then displays the name “guest” for the number associated with the player's position.
In various embodiments, the process 700 provides numerous advantages over manual check-in procedures. Via automatic guest check-in, players are more easily integrated into a gaming table and can immediately begin having activities recorded that can result in comps. Furthermore, guest check-in can occur without the dealer stopping to perform a manual task. Therefore, more hands can be dealt and more money can potentially be made at a casino. Additionally, in various embodiments, via a dealer keypad such as, for example, the dealer keypad 102 of FIG. 4, the dealer can convert a guest to that of a registered player. Once the dealer identifies the guest as a player via, for example, a card swipe, the CPU 50 can apply the activities recorded as a guest to the registered player for purposes of potential comping.
FIG. 8 illustrates a process 800 for automatically checking-out a player (or guest) from a gaming table. In contrast to the procedures described above with respect to FIGS. 5 and 6, the process 800 does not require data entry by a dealer. The process 800 begins at step 802. At step 802, the CPU 50 identifies an idle player position. In a typical embodiment, a player position is determined to be idle if there is a player checked-in at the player position, the player is not in “lobby” as described above, and no gaming activity has occurred for a configurable period of time. For example, for a game of blackjack, it may be determined that no gaming activity has occurred if no hands have been dealt to the player position during the configurable period of time but hands have been dealt to other player positions. In various embodiments, the configurable period of time may be customized for a given establishment such as, for example, a casino.
From step 802, the process 800 proceeds to step 804. At step 804, the CPU 50 checks-out the player from the gaming table. From step 804, the process 800 proceeds to step 806. At step 806, the CPU 50 transmits check-out information to the dealer keypad 102. At that point, the dealer keypad 102 updates the display 208 to reflect that the idle player position is now vacant. After step 806, the process 800 ends.
In various embodiments, the process 800 serves to prevent potential over-comping at gaming tables. For example, until checked-out, a player who is checked-in at a gaming table (but not in “lobby”) may continue to be given credit for receiving hands at the gaming table. By checking out the player after a configurable period of time, over-comping can thereby be prevented.
FIG. 9 illustrates another embodiment of a reporting system using card and chip detection systems similar to those described with respect to FIGS. 1-4. A mini-baccarat tabletop 40a is covered with a felt layer 16a, as previously described with respect to the tabletop 40 and the felt layer 16 of FIGS. 2-4. A dealer's position 42a is positioned along one side of the tabletop 40a, while a plurality of player positions 44a are arrayed in a semi-circle along an opposite side the tabletop 40a. The tabletop 40a additionally includes the dealer keypad 102 and the card-reading apparatus 104 adjacent to the dealer position 42a. 
Consistent with the game of baccarat, each of the player positions 44a provides a betting location for a “banker” bet and a betting location for a “player” bet. Two sensors 12 are positioned in proximity to each of the player positions 44a for purposes of accommodating and detecting each type of bet.
One of ordinary skill in the art will appreciate that baccarat games are often planned by junkets. Junkets serve to organize players that will play baccarat at one or more baccarat tables in casino. Casinos generally compensate junkets by offering a percentage commission that is calculated based on a total sum of money that is put at risk at the baccarat table. In other words, the more money that is bet (either banker or player), the more money the junket can garner.
One scam that sometimes occurs at junket-organized baccarat games involves “balanced betting.” Balanced betting in baccarat refers to a practice of betting approximately equal amounts for both player and banker. Balanced betting can be practiced by an individual player or by multiple players acting in concert. When balanced betting is practiced in concert by all players at a baccarat table, very large sums of money can be bet at greatly reduced risk due to the at least partially offsetting nature of the cumulative bets. Historically, some junkets have recruited players and organized games for the purpose of artificially driving up the total money at risk and increasing the junket's commission. As a result, casinos generally prohibit balanced betting at junket-organized baccarat games.
With reference to FIG. 9, the sensors 12 operate as described with respect to FIGS. 1-4. Thus, although not specifically shown in FIG. 9, the sensors communicate with the processing board 46 and the central CPU 50 as described with respect to FIGS. 3 and 4. In a typical embodiment, the sensors 12 depicted in FIG. 9 are used to determine when a banker bet or a player bet has been placed at one of the player positions 44.
If one or more gaming objects (e.g., chips) are placed over any of the sensors 12 of FIG. 9, the alteration in the state of the A/D converter 26 (FIG. 1) associated therewith will be sensed by the processing board 46 and transmitted to the central CPU 50 and stored. In that way, the central CPU 50 stores each bet and thus can determine a total number of “banker” bets and a total number of “player” bets for a hand. Therefore, the CPU 50 is operable to determine whether a potential balanced-betting situation is present. In a typical embodiment, the CPU 50 determines a potential balanced-betting situation to be present when a total number of “player” bets equals a total number of “banker” bets. If that occurs, in a typical embodiment, the CPU 50 may cause a silent alarm to be sounded or send a notification to the dealer keypad 120. In that way, closer scrutiny may be given to the betting and gaming security may be improved.
FIG. 10 illustrates an embodiment of a bet spot indicator utilizing a bet spot indicator having a light sensor and a plurality of light emitting diodes, which are illustrated and described with respect to FIG. 11. In particular, a gaming table 900 is illustrated. For purposes of illustration, the sensors 12 illustrated with respect to FIG. 3 and described above are grouped together in FIG. 10 as a first group 60. A second group 58 of the sensors 12 is disposed above the first group 60 and adjacent to the player positions 44. A bet spot indicator assembly 950 illustrated with respect to FIG. 11 and described below are grouped together in FIG. 10 as third group 62 of bet spot indicators 950. For purposes of illustration, FIG. 10 shows the third group 62 as a group of progressive bet spots. However, one of ordinary skill in the art will appreciate that, in addition to a progressive bet spot, bet spot indicator assembly 950 may be used with any bet spot on the table layout on a gaming table, such as, for example, a blackjack bet, a pai gow bet, and a proposition bet to name a few non-limiting examples. A dealer keypad 102 and a card-reading apparatus 104 are positioned on the tabletop 900 in proximity to the dealer's position 42.
The dealer keypad 102 and the card-reading apparatus 104 are electronically coupled to the central processing unit (CPU) 50 through a connection 54 and a connection 56, respectively. In various embodiments, the connections 54 and 56 include a transceiver assigned to the table that receives and transmits data to the CPU 50. In the case of the connection 54, the transceiver may relay data intended for the dealer keypad 102 from the CPU 50 to the dealer keypad 102. The transceiver may be, for example, a computing device that communicates via wired Ethernet and/or wirelessly. In various embodiments, the connections 48, 54, and 56 may share a single transceiver.
In a typical embodiment, the bet spot indicator 950 in the third group 62 may be used to indicate whether a bet has been placed in the bet spot. If one or more gaming objects (e.g., chips) are placed over any of the bet spot indicator 950 in the third group 62, the alteration in the state of the A/D converter (not shown) associated therewith will be sensed by the processing board 46 and transmitted to the central CPU 50 for processing. For example, the CPU 50 may send an instruction to bet spot indicator assemblies 950 to illuminate the plurality of LEDs associated with the light sensor on the assembly 950 in response to a change in the light intensity so as to indicate a bet placed in the associated bet spot. In that way, the dealer and player may receive immediate visual feedback that a bet, such as a progressive or proposition bet, is placed in the bet spot.
Each of the bet spot indicator assemblies 950 is coupled electronically with a processing board 46 through a connection 901. The processing board 46 is electronically coupled to a central processing unit (CPU) 50, possibly wirelessly, through a connection 52. In various embodiments, the connection 52 includes a transceiver assigned to the table that receives data from the processing board 46 and transmits the data to the CPU 50. The transceiver may be, for example, a computing device that communicates via wired Ethernet or wirelessly. In a typical embodiment, the CPU 50 is representative of a management system such as, for example, a casino management system, and may be representative of one or more physical or virtual server computers. In a typical embodiment, the CPU 50 stores for and facilitates management of a plurality of gaming tables.
Processing board 46 may be operable to detect changes in light intensity at the light sensors and illuminate the plurality of LEDs of the bet spot indicator assembly 950. In another embodiment, CPU 50 instructs processing board 46 to illuminate the LEDs associated with the light sensor detecting the change in light intensity. In another embodiment, the CPU 50 is operable to perform at least one operation based on a status of the light sensors transmitted to the CPU by the processing board 46. One example of an operation is illuminating the LEDs associated with the light sensor that detects a change in light intensity.
Preferably, each of the bet spot indicator assemblies 950 is monitored continuously, so that any alteration in the state of the A/D converter associated with any bet spot indicator will be sensed by the processing board 46 and transmitted to the CPU for processing.
FIG. 11 illustrates one embodiment of a bet spot indicator assembly 950. In the illustrated embodiment, bet spot indicator assembly 950 generally comprises a cadmium sulphide sensor 960 whose resistance changes in response to light, as powered from a cable through a conductor (not shown). The light sensor 960 pulls against a resistance to create a changing voltage point, in a manner known in the art. This changing voltage point is measured using an Analog to Digital (A/D) converter (not shown) through a conductor and calibrated continuously to detect changes in light through fabrics and changing lighting conditions. The bet spot indicator assembly 950 also contains a plurality of light-emitting diodes 955, which serves as a bet spot indicator and is optically isolated from the light sensor. As shown in FIG. 12, the bet spot indicator assembly 950 is preferably mounted to a gaming table beneath a bet spot 14 associated with a gaming table layout.
FIG. 13 shows a typical progressive system 903. Each gaming table (not shown) in progressive system 903 is constructed to have a control unit 908, a plurality of bet spot indicator assemblies 950 associated with each progressive bet spot on the table, a dealer control unit 985 and a progressive display 975. As shown, the PTC unit 980 (e.g., electronic system) of each gaming table is coupled to a central CPU 970 through a connection 970, which may be hard wired or wireless. The operation of the progressive jackpot may be administered by the central CPU 970, or alternatively by a separate process running on computer 990 coupled to the progressive displays 975 over connection 991, which may be hard wired or wireless. If CPU 970 administers the progressive jackpot of the system, the progressive jackpot value is stored and updated by CPU 970.
Dealer control unit 985 may be configured to receive information related to the bets in the progressive area at each player position at the gaming table and transmit the information to the computer 970. Control unit 985 may then receive confirmation from the computer 970 that the progressive jackpot has been incremented by a predetermined amount based upon the number of player positions placing a progressive bet in the progressive bet spots and update display 975 responsive to the received confirmation.
CPU 970 may be configured to receive information related to a change in light intensity at a light sensor associated with bet spot indicator assembly 950, determine whether a bet spot is covered, and, responsive to a determination that the bet spot is covered, transmit an instruction to the PTC unit 980 to illuminate the plurality of LEDs associated with the light sensor having a change in the light intensity to indicate a bet placed in the progressive bet spot. CPU 970 may also be configured to transmit a notification to increment the progressive jackpot value associated with the progressive system 903.
Continuing with system 903, each gaming table comprises a dealer control unit 985 communicatively coupled to the bet spot indicator assembly 950. In operation, the dealer control unit 985 is configured to transmit notifications to automatically lock and store information regarding a progressive bet placed in the progressive bet spot when the dealer unit is activated. Progressive display 975, such as an LCD display, is positioned proximate the gaming table. In operation, the progressive display 975 displays a progressive jackpot value. In one embodiment, the progressive jackpot value is automatically updated by a predetermined amount when a gaming chip is detected in the progressive bet spot by the bet spot indicator assembly 950 when the dealer control unit 950 is activated to lock the progressive bets.
In operation, a light sensor is positioned proximate a player location on the table top designated for the placement of a progressive bet associated with each player position. If a bet is detected, the plurality of LEDs associated with the at least one light sensor illuminate to indicate a bet has been placed in the location designated for the placement of a progressive bet. Typically, the LEDs are arranged beneath the gaming table layout to surround the location designated for the placement of progressive bets and the LEDs illuminate in a unique pattern.
Alternatively, a light sensor may be positioned proximate a location on the table top designated for the placement of a proposition bet associated with each player position. In such a case, the plurality of LEDs associated with the at least one light sensor illuminate to indicate a bet placed in the location designated for the placement of a proposition bet.
FIG. 14 illustrates one embodiment of a method of visually indicating the presence of a bet in a bet spot. At operation 1000, a change in light intensity is detected via a light sensor on bet spot indicator assembly 950 positioned beneath a gaming table layout on the gaming table in proximity to a player position at a gaming table. The change in light intensity is detected through the layout. Either the CPU or the PTC unit processes the change in light intensity. In response, a notification is transmitted to the bet spot indicator assembly 950 to illuminate a plurality of light emitting diodes (LEDs) positioned beneath the gaming table layout on the gaming table and associated with the light sensor in response to detecting a change in the light intensity at the light sensor.
FIG. 15 shows a typical system 1100 for determining the value of the gaming chip(s) in the bet spot 1101 once a card is dealt to a player. The illustrated system 1100 generally comprises a sensor assembly 1102 configured to determine if a playing card has been dealt to the player occupying the player position associated with bet spot 1101. Sensor assembly 1102 generally comprises a light sensor board 1105 having a cadmium sulphide sensor 1110 whose resistance changes in response to light. Sensor assembly 1102 is communicatively coupled to a control device 1125, possibly wirelessly, through a connection 1126. In addition, the illustrated system 1100 comprises an RFID antenna 1120 surrounding bet spot 1101 and an RFID reader 1125 configured to communicate with the antenna 1120 to determine the amount of the bet in bet spot 1101 using RFID enabled gaming chips (not shown). RFID antenna 1120 is communicatively coupled to an RFID reader 1130 through a connection 1131. In the illustrated embodiment, PTC 1125 and RFID reader 1130 are communicatively coupled to a CPU 1135 over connection 1136 and connection 1137 respectively. PTC 1125 and RFID reader 1130 may exchange information and instructions with CPU 1135, such as a notification of a change in light intensity at sensor assembly 1102 or a determination of the amount associated with the gaming chips placed in bet spot 1101.
In operation, the system is able to record the amount of the player's bet found in bet spot 1101 once the sensor assembly 1102 detects the presence of a playing card (indicating the player has been dealt a hand), which triggers the combination of the antenna 1120 and RFID reader determine the amount of the bet in bet spot 1102. More specifically, the playing card is dealt to a player near the player's bet spot 1101, and therefore covers the cadmium sulphide sensor associated with sensor assembly 1102. The combination of the processing board 1125 and CPU 1135 detect the presence of the card, and thereafter the CPU 1135 triggers the RFID reader 1130 to read the RFID enabled gaming chips found in bet spot 1101. Such an operation allows a casino to track a player's bet amounts more accurately.
In another embodiment, the value of the progressive jackpot in progressive system 903 may be increased by a predetermined percentage of the value of the RFID enabled gaming chip(s) read in bet spot 1101.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
